The Earth is billions of years old and living things found today evolved from what lived millions of years ago. Fossils show what living things used to exist a long time ago. Living things we see today evolved from ancestors that were around a long time ago. Palaeontologists study fossils and are able to date them based on the age of the rock they were found in. Scientists are able to understand what living things existed at the same time and how these living things evolved over time.
